Thor packs a mighty punch
Seven Atlas Copco CDS 8-inch hammers equipped with 10-inch bits and mounted in one assembly drill, made a formidable tool for foundation specialist Anderson Drilling of California. They called it Thor, after the Nordic god, and put it to work on a complex bridge building project near San Diego. The challenge was to install 37 piles ranging from 60 – 108 inches in diameter and 55 – 80 feet deep. The solution was cluster drilling.
Anderson Drilling is a respected and experienced foundation contractor known for tackling big foundation jobs in California. Anderson operates a high quality and well maintained fleet of foundation drills, cranes and the traditional tooling capable of completing these often monumental projects. In order to be more efficient in the recent downturn in the construction economy, Anderson looked at newer technology, specifically Atlas Copco’s 48-inch cluster drill, as a way to speed up the foundation drilling process.
